Re: [MooseFS-Users] "changelog lost !!!" log message

[Jay L. <jl...@sl...>]

Hi,

Just to provide a quick update.  I confirmed that I have enough disk space
and updated MooseFS to the latest and the problem persists. I see nothing
in the kernel logs that coincides with these errors.  The
error always occurs at the top of the hour. (For example 10:00:00, 3:00:00,
21:00:00 or 18:00:00), and occurs at most every 3 hours but often less
frequently than that.  (The time between instances is inconsistent.)

I am still scratching my head on this one.  Any other ideas?

JL
